Abstract: The tolerant parent JZS,susceptible parent T2002 and their F2 generation were used to analysis of the inheritance of water logging tolerance and identification of the linked molecular marker by BSA method (Bulked Segregate Analysis) with the identification index of adventitious root number under water logging in bottle gourd. The results showed that the inheritance of water logging tolerance of JZS was controlled by one pare single dominant gene,and the heterosis was showed in F1 with more adventitious root number than the tolerant parent JZS. Among 600 RAPD and 100 bottle gourd SSR primerstotal number of 18 markers (14 RAPD and 4 SSR) showed the poly- morphism between two parents,and among which one SSR primer of S87/88 was screened a polymorphic lolus (230 bp) between two parents and between tolerant and susceptible bulks.S87/88 showed the significant correlation with the water logging tolerance of the F2 population identified by adventitious root number,and the genetic distance be- tween them was 8.8cM determined by Mapmaker 3.0 software,which provided the useful molecular marker to as- sistant select the new variety with water logging tolerance in bottle gourd.
